RNI is the first only manufacturer of Structural Steel Decking sheets in Sri Lanka. The material used by us is 0.75 Zincaluminium coated steel which is much better compared to galvanized steel available in the market. This is due to the fact that Zincaluminium has 4 times the life time of Galvanize. It has a 1020 mm effective width which is wider than the decking available in the market thereby reducing the number of laps and covering higher area.
RNI Decking could be used in the building construction industry to be highly economical, flexible & strong method of form work and also a reinforced system for composite concrete slabs. It is available in Non Colour and needs no painting or maintenance. Due to the high standard of finish on the surface, ceiling panels are not required underneath the decking, making it a very cost effective method of construction. Suitable to be used in multistory buildings, mezzanine floors etc., since tempory propping is not required in floor concreat work.
